Really? That may have changed in the past few years. Used to be that 
rsnapshot used GNU cp's --link option to copy hourly.1 to hourly.0 after 
rotation. Regardless, you still need a wrapper to handle that rotation.

It's not the multiple replicas that make it a backup system. It's the 
discrete medium that makes it a backup system. If you put your snapshots 
or replicas on the same medium as the original data and that medium 
fails or is corrupted or stolen or burns to the ground then you lose it 
all, originals and snapshots and replicas all together.
